Tip: Anki does not have the "failed cards" concept, but it can be easily simulated. Just add the 'failed' tag to the postponed tags list (edit > deck properties > priorities & postponing). Now, when you fail a card and think it needs rework, type ctrl+e and tag it 'failed'. It will be removed from the reviewing sessions.
